When OOM happen, will dump buddy free areas info, hugetlb pages info, memory state of all eligible tasks, per-cpu memory info. But do not dump slab/vmalloc info, sometime, it's not enough to figure out the reason OOM happened.
So, my questions are: 1. Should dump slab/vmalloc info when OOM happen? Though we can get these from proc file, but usually we do not monitor the logs and check proc file immediately when OOM happened. 2. /proc/$pid/smaps and pagecache info also helpful when OOM, should also be dumped? 3. Without these info, usually how to figure out OOM reason? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
